2 Claims.

This invention relates to calendar devices for pens and pencils, and its general object is to provide a device that may be permanently secured to a fountain pen or a mechanical pencil, or it may be in the form of an attachment for detachable association with any type of writing implement to be carried there-by, for the convenience of the user of the implement in ascertaining the date.

A further object is to provide a calendar device that can be set in an easy and expeditious manner, to indicate a date including the year, month, and the day of the month, but casual displacement of the device from its set position is practically impossible, and the device will in no Way interfere with the use of the writing implement.

Another object is to provide a calendar device for the purpose set forth, that is simple in construction, inexpensive to manufacture, and extremely efficient in operation, use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a side View illustrating a pencil constructed to include the device which forms the subject matter of the present invention.

Figure 2 is a sectional View taken approximately on line 2-2 of Figure 1, looking in the direction of the arrows.

Figure 3 is a sectional view taken approximately on line 3-3 of Figure 1, looking in the direction of the arrows.

Figure 4 is a perspective View of one of the number bearing cylinders for indicating the days of the month.

Figure 5 is a means.

Referring to the drawing in detail, in which we have illustrated a device as being associated with a mechanical pencil, it will be noted that the device includes a tubular casing or housing I that is formed on or otherwise fixed to the pencil barrel A, but the casing may be detachably associated with the pencil or any type of writing implement, as previously set forth.

The casing l is shown as being of a diameter greater than that of the pencil barrel, and the casing has an elongated longitudinally extendperspective View of the setting ing slot 2 therein adjacent its inner end, a relatively short slot 3 adjacent its outer end, and a pair of square cornered openings 4 and 5 between the slots, which together with the openings are arranged in alignment with each other, as clearly shown in Figure l. The inner end of the casing is provided with an annular shoulder and is closed by a disk 6 mounted on the shoulder, while the outer end portion of the casing is interiorly threaded for threadedly receiving a relatively long cap I abutting a disk 8, as clearly shown in Figure 2.

Mounted for rotation in the casing between the disks 6 and 8 for wiping engagement therewith, as well as with each other, are four cylinders indicated respectively by the reference numerals 9, l3, II and I2, and secured to and surrounding the cylinders in the form shown, are bands, the band of the cylinder 9 having the abbreviations of the names of the months thereon, the bands of the cylinders l0 and H, numerals from 0 to 9, to indicate the days of the month and the band of the cylinder l2, numerals indicative of years for at least a period of ten years. The cylinders Hi and II are arranged for the numerals of the bands thereof to show through the openings 4 and 5 respectively, while the abbreviations show through the slot 2, and the the numbers of the band of the cylinder [2 show through the slot 3, it being of course unde stood that the slots and openings 2 to 5 inclusive provide window openings for that purpose, as clearly shown in Figure 1. While the indicia is shown as being applied to bands, it will be obvious that it can be applied directly to the cylinders, in any suitable manner.

The cylinders are provided with annular flanges [3 extending from the peripheries thereof and the flanges provide bearings for the cylinders in that they are disposed in wiping engagement with the casing for spacing the indicia therefrom so as to prevent Wear on the indicia during the rotation of the cylinders, as will be apparent. The confronting faces of the cylinders are counterbored to provide chambers l 4 between the cylinders, as clearly shown in Figure 2, and the cylinders are likewise provided with central bores l5, as well as aligned slots l6 intersecting and radially extending from the bores IS, the slots [6 opening through the ends of the cylinders and terminating short of the circumference thereof, as clearly shown in Figure 4.

The cylinders are of course individually rotated, and for that purpose we provide a headed stem l1 extending through the disk 8 and into the bores l5 for slidable and rotatable movement. Extending transversely through the stem is a pin it engageable with the wall of the slot l6 of any one of the cylinders for rotating the same to position any of the date indicia to show through the Window openings provided by the slots 2 and 3 and the openings 4 and 5.

Sleeved on the stem is a coil spring l9 having its ends engaged with the disk 8 and the head 20 of the stem to cooperate with the outer wall of the cap "I, for normally holding the stem in a position so that the pin I8 thereof is disposed within the chambers M of the confronting faces of the cylinders l0 and II, as clearly shown in Figure 2, the spring acting to resist inward movement of the stem from its normal position, while the head 23 engages the outer wall of the cap when the latter is in place, to prevent outward movement of the stem. The head provides a handle for the stem and is preferably serrated as shown, to provide a firm gripping surface to facilitate rotating the same and the cylinders, and it will be obvious that any one of the cylinders is rotated merely by positioning the pin IS in the slots thereof, and thence rotating the stem through the medium of the head 20.

The cap 1 provides a housing for the outer end portion of the stem, its head and the spring, and an eraser 21 may be mounted on the cap, especially when the device is used with a pencil, as shown, but of course the eraser can be eliminated when the device is used on fountain pens or the like, if desired.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What we claim is:

1. A calendar device for a writing implement, comprising a casing to be carried by the implement and having window openings therein, date indicia bearing cylinders mounted for rotation in the casing for the indicia to show through the window openings, bearing flanges on the periphcries of the cylinders and disposed in wiping engagement with the casing for spacing the indicia from the casing, said cylinders having their confronting faces counterbored to provide chambers between the cylinders, said cylinders having axially disposed bores therethrough and aligned slots radiating from the axially disposed bores, handled means slidably and. rotatably mounted in the axially disposed bores and extending through the casing, a pin fixed to the handled means and receivable in the slots of any one of the cylinders for individually rotating the latter, a cap providing a housing for the extending portion of the handled meansand being removably secured to the casing and a spring cooperating with the cap for normally holding the pin in a chamber between certain of the cylinders.

2. A calendar device for a writing implement,

comprising a tubular casing to be carried by theimplement and having window openings extending longitudinally thereof, date indicia bearing cylinders mounted for rotation in the casing for the indicia to show through the window openings, said casing having one end secured to the writing implement and its opposite end open and threaded therefrom ior a portion of its length, bearing flanges on the peripheries of the cylinders and disposed in Wiping engagement with the casing for spacing the indicia from the casing, said cylinders having their confronting faces counterbored to provide chambers between the cylinders, said cylinders having axially disposed bores therethrough and aligned slots radiating from the axially disposed bores, a stem 'slidably and rotatably mounted in the axially disposed bores and extending through the open end of the casing, a serrated head on the outer end of the stem and providing a handle, a pin transversing the stem and extending upon opposite sides thereof, said pin being receivable in the slots of any one of the cylinders for individually rotating the latter, a disk mounted in the casing against the outermost cylinder, a. coil spring sleeved on the stem and engaged with the head and the disk,

a cap providing a housing for the handled portion of the stem and threaded in the outer end of the casing for engagement with the disk for urging and holding the latter against the adjacent cylinder and the cylinders against each other to hold said cylinders against casual rotation, and said head being engaged with the cap for the latter to cooperate with the spring to normally hold the pin in a chamber between certain of the cylinders.
